The future Doral Police Headquarters site is located at 3719 NW 97th Avenue, Doral, within the approximately 70 acre parcel. The proposed new building and program features are located within a project boundary of roughly 11 acres. The site is owned by the State of Florida (public lands) and operated by the

City of Doral. The site is currently accessed for the police training facility from NW 97th Avenue to the west.

Included within the site are two areas that are functioning as mitigation areas for water storage. Note that for this site to be fully functional for its planned programming, it is recommended that the site be mitigated at a rate greater than the minimum standards. The proposed project seeks to integrate the facility needs to provide a headquarters building, parking, connection to existing vehicular and pedestrian paths, and mitigate stormwater as necessary. The site benefitted as a previous 2021 recipient of the Miami-Dade

County matching grant program as a part of an effort to achieve 30% canopy coverage across the County.

For trees that are within conflict of the proposed project, it is recommended that they are to be relocated elsewhere on the property and for any trees in poor health tat they be replaced as a part of the project design and construction future phases.

I. Site Information

a. Site: As per the Property Appraiser of Miami-Dade County detailed report, the following folio, property address, owner, and land use that will be used to assist with meeting compliance for landscape-related concerns are below. According to the Property Appraiser of Miami-Dade County, this folio is unplatted.

Above: Property Appraiser of Miami-Dade County Folio information.

As per the Regulatory Economic Resources (RER) for Miami-Dade County, all land development within municipalities and in areas of unincorporated Miami-Dade County must comply with Chapter 28, Subdivision Code of Miami-Dade County and Chapter 177, Florida Statutes along with other State and local regulations. Applicants submit new land development to the Plat Committee to be reviewed for compliance with the Subdivision Code of Miami-Dade County and all other State and County legislation.

b. Land Use Consideration (Landscape) As per the Property Appraiser of Miami-Dade County detailed report, the following folio, property address, owner, and land use that will be used to assist with meeting compliance for landscape-related concerns are below.

As per the Property Appraiser of Miami-Dade County property information, the primary land use zone is recorded as light industrial and the primary land use is office building. Within this land use, as per Sec. 33-261 (Ord. No. 79-97, § 1, 11-20-79; Ord. No. 85-87, § 4, 10-1-85; Ord. No. 95-223, § 1, 12-5-95; Ord. No. 03-76, § 1, 4-8-03), the site plan will need to be in compliance with the Minimum Landscaped Open Space, Greenbelts, Trees, and Maintenance codes. As per the Miami- Dade County Landscaping Ordinance, 20 percent of the site is required to be open space. This area to be developed as open space. Landscaped open areas as defined by this municipal code include: entrance features, greenbelts, unpaved passive and active recreation areas, and other similar landscaped open space at ground level. Open space areas may also include tree preservation zones of “natural forest communities” as defined in Section 26B-1 Code of Miami- Dade County. Note that water bodies may be used as part of the required landscaped open space but such water areas shall not be credited for more than twenty (20) percent of the required open space. For this land use, landscaping and trees shall be provided in accordance with

Project: 219421076 Page 2 of 14

II. Miami-Dade County Landscaping Ordinance

Zoning District and Tree Planting Quantities: Chapter 18A of the Miami-Dade County Landscaping Ordinance which requires 15 trees per acre per this zoning district (in addition to street trees). The Miami- Dade County Property Appraiser Detailed Report for the folio indicates that the site is a total lot size of 3,054,263 Square Feet, which is equal to approximately 70 acres. At 15 trees per acre, this will result in needing to meet or exceed at least 1,050 trees for the total site. The approximate area of the proposed project area is 11 acres. Thus, a minimum of approximately 165 trees are to be maintained on site. Should all existing trees remain, replaced, or relocated, the site plan would be maintaining the minimum standards.

Note that the project are is part of the larger folio as aforementioned and currently unplatted and not out parceled and a site plan/tree survey including arborist report are necessary in order to make a final determination on compliance with the Miami-Dade County Landscaping Ordinance.

Tree Survey and Arborist Report: For the purposes of the existing tree inventory and preliminary analysis of impact to the existing site with the proposed plan, the City of Doral Street Tree Inventory was utilized.

The site plan/tree survey must include all trees with a diameter at breast height (DBH) of three (3") inches and greater or trees with an overall height of twelve (12') feet and greater located on the property. The City of Doral inventory does not currently reflect the accurate sizing of the trees or survey quality locations.

In order to comply with the final determination on tree planting designs, the tree inventory information is required to include for each tree the identification and number, scientific name/common name, diameter at breast height (DBH), canopy diameter or square footage, and disposition (to remain, be removed or relocated). For any trees that will be relocated, the current location and proposed locations will need to be reflected as well as a completed DERM, Tree and Forest Resources Section, Tree Location Plan Form with the signed and sealed tree survey and site plans. As such, a full site survey is necessary in order to assess the total existing trees on the property and ensure that the site complies with the total trees required for the land use.

Existing Grant-Funded Trees

This site is a 2021 recipient of the Miami-Dade County Parks, Recreation and Open Spaces Department (PROS) “Growing Roots for Environmentally Equitable Neighborhoods (Green) Miami-Dade County Matching Grant Program”. As a part of this project, a tree planting agreement is held between PROS and the City of Doral. As a municipality, the City of Doral was eligible through the site as it sits on public land as a part of this effort to reach the Million Trees Miami goal of achieving 30% tree canopy. The agreement can be obtained by the City of Doral. Any future work related to the trees will require coordination through the City of Doral as the grantee such as any issues that affect the previously funded trees as the grantee is responsible for the maintenance of the trees after completion of the project in perpetuity.

For an inventory of the existing trees on the project area of this parcel, the trees may be identified on the following website that is part of the City of Doral Open Data Hub, Public Works, City Street Tree Inventories at the below link under the “City Street Tree Inventories” interactive web map:

https://gis-cityofdoral.opendata.arcgis.com/:

As a part of the larger effort to protect, preserve and enhance the tree canopy on public lands across the County, please note the Miami-Dade Urban Foresty Plan can be found at:

https://www.miamidade.gov/economy/library/urban-forestry-plan.pdf

Existing Tree Species: The existing trees planted as per the City of Doral Street Tree Inventory within the area of potential conflict in the project boundary include the following species:

Project: 219421076 Page 4 of 14

Bulnesia arboria (Vera wood)

• Bursera simaruba (Gumbo Limbo) *

• Coccoloba diversifolia (Pigeon Plum) *

• Coccoloba uvifera (Sea Grape) *

• Conocarpus erectus (Green Buttonwood) *

• Ficus aurea (Strangler Fig) *

• Myrcianthes fragrans (Simpson’s Stopper) *

• Quercus virginiana (Live Oak) *

• Sabal palmetto (Cabbage Palm) *

• Swietenia mahagoni (Mahogany) * *denotes Florida native species

Based on a preliminary analysis of the tree inventory information as per the City of Doral Street Tree Inventory, approximately 54 existing trees are in conflict with the site plan as proposed and will need to be relocated. Please see below for a preliminary list of the native trees in conflict:

BOTANICAL NAME COMMON NAME QTY. IN

CONFLICT

Bursera simaruba Gumbo Limbo 5

Coccoloba diversifolia Pigeon Plum 2

Conocarpus erectus Green Buttonwood 27

Myrcianthes fragrans Simpson’s Stopper 13

Quercus virginiana Live Oak 5

Sabal palmetto Cabbage Palm 2

Swietenia mahagoni Mahogany 0

For those in conflict, it is recommended to have them relocated on site. Based on an arborist report, the condition of all trees on site need to be properly evaluated to ensure that those needing to be replaced are properly identified and replaced instead of relocated.

Tree removals: Prior authorization from Miami-Dade County is required for any tree removal/relocation. A tree removal/relocation permit is required for the removal or relocation of any tree within Miami-Dade County note specifically exempt under the Environmental Code of Miami-Dade Conty. As per the Miami- Dade Department of Regulatory and Economic Resources, Division of Environmental Resources Management (DERM), a Site plan/tree survey is mandatory when applying to remove and/or relocate ten

(10) or more trees and may be required for properties that have ten (10) or more trees present. This will assist with determining the trees in conflict that will be required to be relocated on site as well as determining any trees that need to be replaced and planted on the site.

Tree Replacements: As per the matching grant funded trees, new trees that are intended to be replacement trees shall have a minimum overall height of 12-feet and 2-inch caliper at time of installation. If planting Florida native species, trees shall have a minimum overall height of 8-feet and 1.5-inch caliper at time of installation. When installed in roadways, trees shall have a maximum average spacing of 35-feet on center and be placed within 7-feet of the edge of the roadway pavement and/or where present, within 7-feet of the sidewalk. Trees shall be installed in a way that complies with site triangle regulations and should not be planted within no planting zones. If trees are proposed under overhead power lines, they shall have a minimum overall height of eight (8) feet and a minimum caliper of one-half (1.5) inch at the time of planting.

The maximum average spacing in this case shall be 25-feet. All trees shall have and shall be maintained with a trunk clearance of four (4) feet (no multi-trunk).

III. Landscaping and Buffers

As per the City’s Land Development Code, the landscape plans must meet or exceed all requirements of chapter 71 – Landscaping and Buffers as per Chapter 71.

Quality of Landscape: In order to promote a high quality of landscape, the intent of any future plant material incorporated for the site is to be guided by the principles from the code. To that end, irrigation systems that conserve the use of potable and nonpotable water supplies and restrictions on the amount of lawn areas are recommended. The canopy trees on site are preserved to the extent possible in order to provide visual definition and hierarchy of roadways throughout the design. In addition, canopy trees to provide shade and a visual edge of vehicular circulation areas. The existing roadways are planned to remain to the extent possible and in turn, prevent the destruction of the community's existing tree canopy and promote its expansion. To the extent possible, the site plan conserves the existing tree canopy to provide cooling through the provision of shade from tree canopy and helping to reduce temperatures through these measures. Through its design, the project landscape concept is to promote the right tree in the right place to avoid problems such as clogged sewers, cracked sidewalks, damage to structures, and power services interruptions. Additionally, the goal of the landscape is to enhance the aesthetic appearance

Project: 219421076 Page 7 of 14 of the development of the site through the use of plant material, thereby protecting and increasing property values within the community, and protecting the site.

Buffers: A landscape buffer strip at least 15 feet in width is required along the frontage with all public streets. This buffer shall contain landscaping only; parking spaces, signage, above ground utilities and other structures are not allowed. As such, the project does not propose to develop the property in a manner such that would prevent the buffer strip along public streets is being proposed at this time. Note that the site is adjacent to the public City road NW 97th Ave to the west of the site where the main entrance and exits to the facility are planned.

Planting Material: Promote the use of trees and shrubs for energy conservation by encouraging cooling through the provision of shade and the channeling of breezes, thereby helping to offset global warming and local heat island effects through the added absorption of carbon dioxide and reduction of heat islands. The planted material is designed to contribute to the processes of air movement, air purification, oxygen regeneration, groundwater recharge, and stormwater runoff retention, while aiding in the abatement of noise, glare, heat, air pollution and dust generated by major roadways and intense use areas. As per the Terms and Conditions of the matching grant with the City of Doral, all trees were agreed upon to be planted as canopy natives or Florida-friendly trees. For the purpose of this grant, palms are not considered canopy, and as such are not eligible for grant reimbursement or match for these projects. All trees must be planted on public property within Miami-Dade County in adherence to Miami-Dade County’s Landscape Ordinance (Chapter 18-A and Chapter 18-B). For the replacement of any new trees, the same standards will need to be met.

Wetland Area Planting: The site currently within the project area has two areas where the site includes water mitigation. The area to the west while pending an official verification of wetland determination, will likely require wetland area planting. It is recommended that a final determination be made. In addition, that any exotic plant species be assessed and removed to reduce the negative impacts of exotic pest plant species as per the Land Development code. In order to make a wetland project determination, it is recommended that a bio assessment be considered. Any future planting in wetland areas will also be impacted by the quality of the wetland and mitigation amount for the site and must be factored into any future development. Within Miami-Dade County, wetland area planting is critical to the environmental considerations of the site. The project should focus on the enhancement of wetland area plantings as vital site functionality. A final determination will need to be made with Miami-Dade County Department of Environmental Resources Management (DERM) and coordinated with the South Florida Water Management District (SFWMD).

Specimen Trees: As per the City’s Land Development Code, the landscape plans must meet or exceed all requirements of chapter 71 – Landscaping and Buffers as per Chapter 71 as they relate to specimen trees as defined as any trees with individual trunk which has a diameter at breast height of 18 inches or greater, but not including the following:

(1) All trees listed in section 24-60(4)(f) of Miami-Dade County Code;

(2) Nonnative fruit trees that are cultivated or grown for the specific purpose of producing edible fruit, including, but not limited to, mangos, avocados, or species of citrus;

(3) Nonnative species of the genus ficus; and

(4) All multitrunk trees in the palm family, except Accelorrhaphe wrightii which have a minimum overall height of 15 feet.

IV. Landscape Plans

As per the City’s Land Development Code, the landscape plans must meet or exceed all requirements of chapter 71 – Landscaping and Buffers as per Chapter 71, Landscape plans shall be approved by the city, department of planning and zoning, and, where required pursuant to subsection (d) of this section, an irrigation plan shall be approved by the building department, prior to the issuance of any building permit or paving for new parking areas or expansion of existing parking areas.

Project: 219421076 Page 8 of 14

Vegetation Survey and Wetland Determination: For this site, the landscape plans fall under the category “all other development” and must include vegetation survey accompanied by aerial photograph which outlines the subject site without obscuring its features. Note that because the site falls within a municipality, the survey shall be verified by the departments or boards as deemed appropriate by the city.

The vegetation survey shall provide the relevant information as outlined in the municipal code including all existing trees of a minimum two-inch diameter at breast height or ten-foot height; or for native trees of a minimum 1½-inch diameter at breast height or eight-foot height; including those which are proposed to be removed, relocated or preserved on site, in accordance with the requirements of this Land Development Code and section 24-60 of the Miami-Dade County Code. The boundaries of any native habitat, native plant community, native plant species, and/or natural forest community and associated understory that exists on site, as determined by the department of environmental resources management.

Above: Preliminary proposed site plan illustrating existing trees, relocation of trees to accommodate new program elements, proposed stormwater mitigation and wetland areas and lake and vehicular and pedestrian circulation tying into the existing site where feasible.

Project: 219421076 Page 9 of 14

Irrigation Plans: An irrigation plan shall be submitted if a sprinkler system is required by this Land Development Code, or where an irrigation system is to be provided regardless of code requirements.

Where a landscape plan is required, an irrigation plan shall be submitted concurrently. The irrigation plan(s) will need to comply with the following minimum standards: Be drawn on a base plan at the same scale as landscape plans; delineate landscape areas, major landscape features, and hydrozones;

delineate existing and proposed structures, parking areas or other vehicular use areas, access aisles, sidewalks, driveways, the location of utilities and easements, and similar features; Include water source, design operating pressure and flow rate per zone, total volume required for typical depths of application, and application rate; include locations of pipes, controllers, valves, sprinklers, back flow prevention devices and electrical supply; and include irrigation details as per (Ord. No. 2007-12, exh. A(ch. VII, § 4), 8-22-2007).

Landscape Maintenance: As per section 71-8 -Landscape Maintenance, all landscaping shall be:

Installed in compliance with the landscape requirements of this chapter and additional, applicable regulations found in this Code, as well as supplemental conditions imposed as a result of approvals obtained through processes established in chapters 53 and 68 of this Code, if any; Maintained, in accordance with this chapter and additional, applicable regulations found in this Code, as well as professional trimming standards, and kept free from refuse, debris, litter, dead/dying plant material, infestation of rodents, insects, and/or other pests, and/or undesirable vegetation, so as to foster the shape and size, and ensure the health, of the corresponding species of planting; and Sufficiently fertilized and watered to maintain the plant material in a healthy condition. If any tree or plant dies which is being used to satisfy current landscape code requirements, such tree or plant shall be replaced with the same landscape material or an approved substitute.

As per the agreement with the 2021 Miami-Dade County Parks, Recreation and Open Spaces Department (PROS) “Growing Roots for Environmentally Equitable Neighborhoods (Green) Miami-Dade County Matching Grant Program”, the City of Doral is responsible for the maintenance of the existing trees in perpetuity. Therefore, future development of the site should take into account accommodating the existing trees within the property even if relocation is necessary to accommodate new building or other site elements.
